ABSTRACT:
In a four-link suspension for a ground vehicle, of the type which utilizes a lower pair and an upper pair of connecting links to attach and stabilize a rigid axle of a vehicle in fore, aft, and rotational directions. The improvement to which comprises the addition of a swivel arm, having two ends, and interposed between a pair of links at one end, so that, one end of each link attaches to a corresponding end of swivel arm. The swivel arm has a center pivot axis and attached base mount, which is securely affixed to the approximate middle laterally of the rigid axle or chassis, whichever location is the most desireable to mount the swivel. When looked at from above the impression created is that of a V or U shape from the pair of links and the swivel where they connect. The general purpose of the swivel is to eliminate any bind in the suspension connecting links by permitting one link of the pair to push past, and the other link to pull away from, the swivel center axis. This motion allows the rigid axle to tilt freely from side to side in relation to the vehicle's body, through the full range of vertical suspension travel, when the vehicle is traversing uneven terrain, or leaning when rouning a curve. Plus, the swivel allows for almost infinite mounting angles and lengths of the connecting links, for frame, chassis, or body mounting location considerations, or high performance setup, tuning, and adjustment.
